I think its more fundamental than that.
I have a DigiTrack TruTrack fitted to mine and connected to a Garmin 796,
previously
a AVMAP EKP V, and it needed the RMB and RMC data from these to work. Id
have to check but I dont think the GPS Pucks give out those messages.
If you have the manual then the 4800 baud is recommended so as not to overrun
the
input processing of messages and giving false steering.
The Pucks can be programmed as you say but you need to make sure that the new
settings
are retained, usually with an internal battery which if not retaining
its change will lose the almanac and any changes over time as the battery
deteriorates.
The TrueTrack needs RS232 at +/- 12v most pucks are 5v logic levels and wont
drive
it.
f you are only using a puck I guess you are not using the track following from
a GPS mode but wish to use the internal Magnetometer to steer a magnetic track
and you will need the RMB and RMS messages from the GPS to set it up to start
with after that it should just work from the internal magnetometer.

any experts out there that can tell me whether the Garmin GPS 18x 5Hz puck
that I have been offered, will work as a feed to it? As far as I can understand
---From the various manuals, the Trutrak can only be set up to 9600 baud,
whereas
the default baud in the 18x 5Hz is 19200. It seems possible to reprogram
the 18x 5Hz to 9600 baud but the process looks very complicated for those of us
not used to Garmin code (and who also don't have a PC with serial port!)!
Alternatively,
are there any simpler 'plug and play' GPS 'pucks' that have been
found to work well with the Trutrak? Thanks!
